The ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 . The store has 90 BMX bikes . How many mountain bikes does the store have ?

Answers

Answer: 60

Step-by-step explanation:

From the question, we are informed that the ratio of BMX bikes in a sporting goods store to mountain bikes is 3 to 2 and that the store has 90 BMX bikes .

To calculate the number of mountain bikes that the store has goes thus:

= 2/3 × 90

= 2 × 30

= 60 mountain bikes

Two neighbors in a rural area want to know the distance between their homes in miles. What should the neighbors use as a conversion factor to convert this distance to miles ?

Answers

Answer:

1 foot = 0.000189394 miles

Step-by-step explanation:

The two neighbors in the rural community could measure the distance between their homes first in feet. So that the value in feet can now be converted to miles by multiplying it by 0.000189394.

Since,

1 foot = 0.000189394 miles

Let us assume that the distance between the two houses is 500 feet, then;

1 foot = 0.000189394 miles

500 feet = x miles

x = 500 x 0.000189394

= 0.094697

So that for the considered example, the distance is approximately 0.095 miles.

Thus, the required conversion factor is;

1 foot = 0.000189394 miles

la expresión que se muestra abajo re presenta la utilidad en la producción de una nueva libreta profesional ,¿para que el valor positivo "X" la utilidad resulta igual a cero?
a)10
b)10/9
c)770/9
d)670/9
ayúdenme porfavor

Answers

Answer: a) 10

Step-by-step explanation:

Buscando en google, encuentro que la expresión es:

C(x) = 9*x^2 - 80*x - 100

Queremos encontrar el valor de x (positivo), tal que esa expresión sea igual a cero, entonces tenemos que resolver:

9*x^2 - 80*x - 100 = 0.

Para ello podemos recordar la ecuación de Bhaskara, que para una ecuación de la forma:

a*x^2 + b*x + c = 0

Las soluciones son:

[tex]x = \frac{-b +-\sqrt{b^2 - 4*a*c} }{2a}[/tex]

en este caso, tenemos:

a = 9

b = -80

c = -100

Entoces, las soluciones van a ser:

[tex]x = \frac{-(-80) +- \sqrt{(-80)^2 - 4*9*(-100)} }{2*9} = \frac{80 +- 100}{18}[/tex]

Entonces las dos soluciones son:

x = (80 - 100)/18 = -20/18 = -10/9

Esta solución la descartamos, pues es negativa. La otra solución es:

x = (80 + 100)/18 = 180/18 = 10

La opción correcta es a: 10

Answer:

1. Number 1 and 2 and 4 is a function, 2. number 1 is a function

Step-by-step explanation:

1)To know if it's a function or not run vertical lines through multiple places of the graph. If it is a function every single time you do the vertical line test it should only go over the line once. If you do the vertical line test on 3 you will see that it went over the line on the graph, so we know not a function. Graphs 1, 2, and 4m however, are different, when you do the vertical line test on those graphs it only goes over them once.

2) Choice (1) is a function because when drawing vertical lines through the graph it only goes over one.

Choice (2) is not a function because when drawing vertical lines through the graph it covers two points on the graph.

Choice (3) is not a function because when drawing vertical lines through the graph it goes over multiple points.

Choice (4) is not a function because when a vertical line is drawn, it goes over more than one point on the graph.

The vertical test is a way to determine if it is a function.

When looking at a table functions are one-to-one and many-to-one

Non-functions are one-to-many and many-to-many

1 Admission to the local movie theater is $3 for each child and $7 for each adult. A group of 12 people pay $64 admission. How many children are in this group?

Answers

Given:

Admission to the local movie theater is $3 for each child and $7 for each adult.

A group of 12 people pay $64 admission.

To find:

The number of children in a group.

Solution:

Let the number of children be x and number of adults be y.

According to the question,

Total persons : [tex]x+y=12[/tex] ...(i)

Total cost : [tex]3x+7y=64[/tex] ...(ii)

Multiply equation (i) by 7 and subtract the result from (ii).

[tex]3x+7y-7(x+y)=64-7(12)[/tex]

[tex]3x+7y-7x-7y=64-84[/tex]

[tex]-4x=-20[/tex]

Divide both sides by -4.

[tex]x=5[/tex]

Therefore, the number of children is 5.

If Jack wants to retire with $1,000 per month, how much principal is necessary to generate this amount of monthly income if the interest rate is 6% compounded monthly?

Answers

Answer:

He needs to learn the disciplinary principal

Step-by-step explanation:

The principal is necessary to generate this amount of monthly income is $497.

Given that, Jack wants to retire with $1,000 per month.

What is the compound interest?

Compound interest is the interest on savings calculated on both the initial principal and the accumulated interest from previous periods.

The formula used to find the compound interest = [tex]Amount=Principal(1+\frac{R}{100})^{nt}[/tex]

⇒ 1000 =P[tex](1+0.06)^{12}[/tex]

⇒ 1000=P×2.012

⇒ P=1000/2.012

⇒ P=$497

Hence, the principal is necessary to generate this amount of monthly income is $497.

Divisor = 42

Quotient = 28

Remainder = 4

A quotient of 28 simply means that a number divided by 42 would have a value that is equal to 28 without any remainder.

Let the unknown number be X

X = (42*28) + 4

X = 1176 + 4

X = 1180.

Method II

Y/42 = 28

Cross-multiplying, we have;

Y = 28 * 42

Y = 1176

Given that the remainder is 4

X = Y + 4

X = 1176 + 4

X = 1180.

Therefore, the number is 1180.

V5. Suppose you invest $5,000 at 9% interest, compounded annually, for 10 years. Determine the future value of your investment, using the compound interest formula.

Answers

Answer: $11836.8

Step-by-step explanation:

Given. That :

Amount invested = $5000

Interest rate = 9% = 0.09

Period = 10 years, compounded annually

Using the compound interest formula :

A = p(1 + r/n)^nt

A = final amount

P = principal or invested amount

r = rate of interest

n = number of times interest Is applied per period

t = period

A = 5000(1 + 0.09/1)^(1*10)

A = 5000(1.09)^10

A = 5000 * 2.36736367459211723401

A = 11836.81837296058617005

= $11836.8
